(FIXED) Upload Speed aren’t the same as before

I have a NETGEAR CM500 cable modem and a NETGEAR WNDR4000 wireless router, and I have been using them for quite some time with absolutely no problems. I have the Blast! plan with 200mbps download and advertised for 10mbps upload speeds. While my download speeds are great (matches to my plan), I am not getting the upload speeds I used to have. I have a record of my speed tests I’ve done back in May where I was getting my upload speeds to 10 mbps, as I should have been. Then I was gone for the summer and put my plan on vacation mode to save money, then when I came back in August, my download speeds were fine, but my upload speeds are now around 5-6 mbps, and I have done everything that I could possibly do (restated modem/router, factory reset, disconnected and reconnected). No matter what I do, I can’t get my upload speeds back up. When I attempt to navigate through the Xfinity troubleshooter, it keeps prompting me to upgrade my modem for it “can no longer keep up with the internet speeds” even though my modem can (even when I go through the upgrade page, it says the modem is compatible with my plan), and I can’t get around that to get the troubleshooter to do anything helpful. I do enjoy playing video games and I do work online quite a bit, so the upload speed is important for me, and I understand that 5-6 mbps is usually good enough for most things, but I want to get what I’m paying for. I’m not sure what more I can do, any advice would be greatly appreciated, thank you !

Re: Upload Speed aren’t the same as before

FIXED: I was able to resolve this issue with not-to-expectations upload speeds and inaccurate internet/modem troubleshooter by “activating” my modem again (see activation page for self-installing your modem). This will require your modem’s MAC number. After about 5 minutes, I got “You’re all set!” page and when testing my speeds again, I was getting my 10 mbps and when I do the internet diagnostics, it now says there are no issues. Hope this will help others that also have this problem!

In short, reactivate your modem through the Xfinity self activation portal fixed this issue.

Connect it to the coax line and power it up. Let it fully sync up with the system ("DS, "US", and the "Online" lights are steadily lit). Connect a computer to it and open up a browser. You *may* see their "Walled Garden" modem self registration page. If so, follow the screen prompts. Have your mobile telephone number, your Xfinity username and password or the account number and telephone number associated with your Comcast account handy.

If not, try calling 1-855-652-3446. That is their device activation line.

If that doesn't work for you, you can call 1-800-comcast and tell a rep that you would like to have a new modem provisioned for service. Have the RF / CM / HFC MAC address and the serial number of it handy when you call.
